Hi, The Seam Cron module has many providers and I'd like to test each provider by reusing the same test suite (Arquillian), but just having a different provider on the classpath . Kind of TCK style I think. So I would have several provider projects, plus a tck project containing all the common test classes. I guess then each provider project would depend on the tck (scope: test) so that the tck tests, plus any of its own unit tests are all run during that provider's test phase. My concerns with this so far are: 1. I think I will need a test suite with the test classes in src/main/java (rather than src/test/java) so that the provider can get those classes onto its own classpath during testing. Will Arquillian work OK like that (ie: does it have maven integration which specifically looks under src/test/java only)? 2. The classes in the test suite have a hard-coded @Deployment, and I'm not sure how I'd go about customising that place a different provider class on the classpath. I don't want to have to force my providers to extend every test case just to customise the deployment. 3. Am I going about this all wrong? Cheers for any advice you can give me. Pete R
